I am finding the minimum coefficient μ between tires and road so that cars do not slide off. I have my equations for ƩFy and ƩFx and I know μ = [fs]/[/N]
So I would need to use cramer's rule on my equations to find fs and N.
But I am not sure how to use cramer's rule for my equations.
ƩFx = Nsinθ -fscosθ = mv2/r
ƩFy = Ncosθ + fssinθ = mg
The Attempt at a Solution
I actually already have the answer but im not sure how to use cramer's to get to it.
fs = m(gsinθ-v2/r*cosθ)
N = m(v2/r*sinθ+gcosθ)
